How to configure static IP in linux bridge mode

This article mainly shares with you the method of configuring static IP in Linux bridge mode. I hope it can help you.

1: Bridge mode

VMware bridge mode is to transfer the virtual network adapter of the virtual machine to the physical network adapter of the host. The virtual network in the virtual machine The adapter provides direct access to the external network through the physical network adapter in the host. In short, it is like adding a new, independent computer to the LAN. Therefore, the virtual machine will also occupy an IP address in the LAN and can communicate with other terminals. Bridged mode network connections support both wired and wireless host network adapters. If you want to treat the virtual machine as a completely independent computer and allow it to communicate with other terminals on the network, then bridge mode is usually the easiest way for the virtual machine to access the network.

Two: Set up the network adapter

## Three: Modify the configuration file and set a static ip

1: Check the network card interface name ifconfig | more or ip addr | more

[root@localhost ~]# ifconfig | more  
eth0      Link encap:Ethernet  HWaddr 00:0C:29:5A:71:6D    
          inet addr:192.168.1.123  Bcast:192.168.1.255  Mask:255.255.255.0  
          inet6 addr: fe80::20c:29ff:fe5a:716d/64 Scope:Link  
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1  
          RX packets:5631 errors:0 dropped:0 overruns:0 frame:0  
          TX packets:324 errors:0 dropped:0 overruns:0 carrier:0  
          collisions:0 txqueuelen:1000   
          RX bytes:398905 (389.5 KiB)  TX bytes:27775 (27.1 KiB)  
lo        Link encap:Local Loopback    
          inet addr:127.0.0.1  Mask:255.0.0.0  
          inet6 addr: ::1/128 Scope:Host  
          UP LOOPBACK RUNNING  MTU:16436  Metric:1  
          RX packets:230 errors:0 dropped:0 overruns:0 frame:0  
          TX packets:230 errors:0 dropped:0 overruns:0 carrier:0  
          collisions:0 txqueuelen:0   
          RX bytes:19722 (19.2 KiB)  TX bytes:19722 (19.2 KiB)

2: Edit the network card file vim /etc/sysconfig/network-scripts/ifcfg-eth0

As shown in the picture above, my network card name is eth0, then the corresponding file name is ifcfg-eth0

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0   
DEVICE=eth0   #网卡接口名称  
BOOTPROTO=dhcp  #系统启动地址协议   dhcp：DHCP动态地址协议  static：静态地址协议  
HWADDR=00:0c:29:5a:71:6d  
IPV6INIT=yes
NM_CONTROLLED=yes
ONBOOT=yes   #系统启动时是否激活网卡接口  
TYPE=Ethernet
UUID="793813e9-4cbd-4ae1-a1de-f9f38b8369ee"
USERCTL=no
PEERDNS=yes

1. Modify BOOTPROTO and ONBOOT options

2. BOOTPROTI=static

3. ONBOOT=yes

Then add the following content to the file

IPADDR=192.168.1.123  #静态ip,添加前先ping一下该ip,ping不通才能使用,确保唯一  
NETMASK=255.255.255.0  #子网掩码  
GATEWAY=192.168.1.1   #网关

The complete version of the configuration file is as follows

[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0   
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:0c:29:5a:71:6d  
IPV6INIT=yes
NM_CONTROLLED=yes
ONBOOT=yes
TYPE=Ethernet
UUID="793813e9-4cbd-4ae1-a1de-f9f38b8369ee"
USERCTL=no
PEERDNS=yes
IPADDR=192.168.1.123  
NETMASK=255.255.255.0  
GATEWAY=192.168.1.1

3: Restart the network service network restart

[root@localhost Desktop]# service network restart  
Shutting down interface eth0:                              [  OK  ]  
Shutting down loopback interface:                          [  OK  ]  
Bringing up loopback interface:                            [  OK  ]  
Bringing up interface eth0:  Active connection state: activating  
Active connection path: /org/freedesktop/NetworkManager/ActiveConnection/9  
state: activated  
Connection activated  
                                                           [  OK  ]

Four: This Open cmd on the machine to test ping 192.168.1.123

C:\Windows\System32>ping 192.168.1.123  
正在 Ping 192.168.1.123 具有 32 字节的数据:
